Spot lamp



FIG. 1 is a perspective view of the spot lamp showing the new design;

FIG. 2 is a right side view of the design of FIG. 1, which is a mirror image of the left side view of the design of FIG. 1; and,

FIG. 3 is a top view of the design of FIG. 1. 

I claim the ornamental design for a spot lamp, as shown and described.
